Tittabawassee River and Flood Plain SOW - State of Michigan

d. A lower priority will be placed on the infrequently flooded areas (e.g. due to
higher property elevations and distance from the River bank), on current land
uses with less exposure potential, and areas in the Floodplain that have not
been developed; and
e. The prioritization may change based on the conclusions that are drawn from
data that are collected (i.e. an iterative approach).
2. The timing of RI activities may be affected by the need to obtain permission for
access to property, the requirement to obtain permits from governmental agencies,
weather and other conditions which Dow cannot control.
E. Current and Reasonably Anticipated Receptor Identification:
Human populations and ecological habitats that come in contact with chemicals of
concern through contact with Tittabawassee River Sediment and Floodplain soils will
be characterized. If present, any observable impacts to ecological habitants or
receptors will be described.
The following characteristics will be identified:
1. Current and reasonably anticipated future human use of or access to the
Tittabawassee River and Floodplain including, but not limited to:
a. Types of current and reasonably anticipated future uses (e.g. residential,
commercial, zoning/deed restrictions, etc.);
b. Any use restrictions relative to the Tittabawassee River and Floodplain and
the locations where significant concentrations of chemicals of concern are
present; and
c. Evaluation of other use patterns relative to potential human exposure
pathways.
2. A general description of the ecosystem overlying and in proximity to the
Tittabawassee River and Floodplain including, but not limited to:
a. Location and size of major habitat types (e.g., streams, wetlands, forested
areas);
b. Several species composition and relative abundance of plant and animal
species that utilize these habitants;
